Eumorpha megaeacus is a moth of the family Sphingidae.

Distribution

It is found throughout most of Central America and South America, from Suriname, Venezuela, French Guiana, Ecuador, southern Brazil and Bolivia to Nicaragua, Costa Rica and Mexico. Occasionally strays can be found as far north as Texas.^[2]

Description

The wingspan is 105–121 mm. The upperside is dark and can be distinguished from other Eumorpha species by the presence of a conspicuous, but ill-defined, longitudinal brown band running parallel to the hind margin from the wing base on the forewing upperside.
